The DADCQ protocol utilizes the distancemethod to select forwarding nodes. The performance of thismethod Depends heavily on the value of the decision threshold, butit is difficult to choose a value that results in good performanceacross all Scenarios. Node density, spatial distribution pattern, andwireless channel quality all affect the optimal value. Broadcastprotocols Tailored to vehicular networking must be adaptive tovariation in these factors. The aim of this work is to give betterVANETs routing mechanisms, this research gives an overview ofVehicular ad hoc networks (VANETs) and the existing VANETrouting protocols; mainly it focused on vehicle to vehicle (V2V)communication and protocols. Broadcast protocols tailored tovehicular networking must be adaptive to variation in thesefactors. The proposed approach facilitates impact analysis ofdistance dependent DSRC fading channel and application-levelanalysis.
